How do I choose a solar inverter size?
To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.
Is there a difference between inverter size and solar panel capacity?
However, this should always be within the recommended ratio. This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter.
Why is there a'mismatch' between inverter size and solar panel capacity?
This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter. It’s critical for an oversized system to remain within the correct ratio, as this not only impacts efficiency, but also your eligibility for government solar incentives.
What does a solar inverter do?
The inverter converts the DC electricity generated by your panels into AC power for use in your home. An undersized or oversized inverter can lead to energy losses and lower overall system performance. In this guide, we’ll explain how to properly size your inverter for your solar panel system.
Should a solar inverter be oversized?
However, slight over-sizing of the solar panels compared to the inverter capacity (up to 133% under certain guidelines) can sometimes yield better overall efficiency due to the variable nature of solar irradiation throughout the day. The ratio for inverter sizing often depends on specific system requirements and local regulations.
How much power does a solar inverter produce?
Using the example of ten 300-watt panels, your total power output is 3,000 watts. Solar inverters have an efficiency curve, which shows how efficiently they convert DC power from the solar panels into AC power for your home. In general, look for an inverter with an efficiency rating above 95%.
